Answer:

Hi! I believe this is your answer:

$750

Step by step explanation:

interest + interest = total interest

0.08*x + 0.09*(9000-x) = 750 dollars

0.08x + 810 - 0.09x = 750

-0.01x = 750 - 810 = -60 ====> x = %28-60%29%2F%28-0.01%29 = 6000.

Final answer:

$6000 was invested at 8%. The rest 9000-6000 = 3000 dollars were invested at 9%.

Check. 0.08*6000 + 0.09*3000 = 480 + 270 = 750 dollars.

Vikki [24]

Step-by-step explanation:

1) A number m is at least four

m ≥ 4 ['at least' = ≥ symbol]

2) 4x ≤ 20x; x=2

4(2) ≤ 20(2)

8 ≤ 40

[Im not sure if this is a solution or and inequality :/ ]

3) x < 5

--> On the line, draw the number 0, and the number five. 'x < 5' also means 'x is less that five.' So, draw a dot over the line before 5, and make an arrow going to the left of the page,

Answer:

At least 11 two-point baskets

Step-by-step explanation:

In the current game, she has scored 24 points so far.

Difference $=46-24=22$ points

$22\div 2=11$

two-point baskets.
